Hillsboro Ice Dams: Melting on Days It Never Thaws
At Hillsboro's elevation the air can stay below freezing all day while direct sun still melts the top of the snowpack. That meltwater runs down under the pack, reaches a shaded eave, and refreezes — on a day the thermometer never rose above freezing.
Depth makes it worse. A Washington County roof can carry several feet of pack, and all of that is a reservoir sitting above an eave that never sees sun.
Ice-barrier practice in Washington County
Snow retention above doors, walkways and parking is a requirement in most Washington County jurisdictions for good reason: a release off a metal mountain roof is a serious event, not an inconvenience.
What a Crew Does on a Hillsboro Roof
The first pass is assessment: eaves, valleys, gutter line and any interior staining, all photographed with timestamps. You see what the crew sees, and the rate and likely hours are agreed before work begins.
Steam then takes the dam off in sections, prioritizing wherever water is actively backing up behind it. The gutter trough and downspout are cleared through to daylight on the same visit, because a clear eave over a frozen gutter is a temporary fix.
What gets photographed, and why it matters later
Before the lance comes out, the crew shoots the dam from the ground and from the roof, the icicle line, any staining visible inside, and the specific courses where water is tracking under the shingles. Timestamps are on every frame.
That record is the whole case if a claim follows. An adjuster arriving in March sees a dry roof and a stained ceiling; the photographs are what connect the two, and they are what a maintenance-exclusion denial runs into.
How long a removal actually takes
A single-story eave with a thin dam and clear gutters is often an hour or two. A two-story Hillsboro house with ice standing a foot deep across the front, frozen downspouts and a valley packed solid is most of a day for a two-man crew. The honest answer on the phone is a range and the reason for it, not a number designed to win the booking.
The estimate is revised out loud if the roof turns out worse than it looked from the ground, before the extra hours are worked rather than after they appear on the invoice.
What steam actually does
A steam unit delivers water at roughly 290°F at a pressure low enough to rest your hand in the plume. It cuts a channel straight through the ice and lifts the dam off in sections, right down to the shingle. The heat does the work, not force, so granules, seal strips and flashing come through untouched.
That is the whole difference between steam and the hot pressure washers often sold as steam. A pressure washer cuts ice fast because of its pressure — and that same pressure strips the granules off asphalt shingles and drives water up under the courses. One method removes ice. The other removes ice and roof.

Washington County Coverage From Hillsboro
Crews working Hillsboro cover the adjoining communities on the same route — Cornelius, North Plains, Forest Grove, Gaston and Sherwood — so a storm week usually means one truck handling several addresses in Washington County rather than separate trips.
Nearest hub towns with their own crew pages: Beaverton, Tigard, Portland, Lake Oswego, Oregon City, McMinnville.
When a storm hits Washington County, crews are dispatched by severity rather than by call order — water already inside the house goes first.
If water is already inside a property in Hillsboro, call (888) 561-9664 rather than filling in a form — the phone is faster and leaks jump the line.
